## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
Embodiments of the present invention generally relate to image processing and related techniques, and more particularly, to a method and apparatus for an improved workflow for digital image editing.
2. Description of the Related Art
Digital image editing is the process of altering images. A feature common to many graphics editing software, such as ADOBE® PHOTOSHOP® Elements, involves the use of layers to perform various operations. Every image has at least one layer. When an original image is first opened, a layer comprising the image is created, called a background layer. Layers allow a user to add components and adjustments to an image and work on the components and adjustments one at a time without permanently changing the original image. For each layer, color and brightness may be adjusted, special effects may be applied, layer content may be repositioned, opacity and blending values may be specified, and so on. The stacking order of the layers may be rearranged, layers can be added and removed, and layers may be linked (grouped) so they may be visible and worked on simultaneously.
The use of layers enables maximum flexibility for the user while maintaining non-destructive editing. In non-destructive editing, the original image is not modified in the course of editing. Instead, layers are used to separate different elements of an image. Different kinds of layers exist, each representing a component part of the picture, either as pixels, showing an image (called a pixel layer) or as modification instructions (adjustments), which apply an effect (called an adjustment layer). These layers are stacked on top of one another and depending on the order, determine the appearance of the final picture. A layer can have a certain transparency/opacity and a number of other properties. A layer may have more than a hundred different possible settings. This gives the user a lot of flexibility with editing. An adjustment layer typically applies a common effect like brightness or saturation to other layers. However, because the effect of an adjustment is stored in a separate layer, it is easy to apply that adjustment layer to other layers to test different alternatives, without changing the original layer(s). In addition, an adjustment layer can be edited easily, so the effect can be applied to just a part of the image. This can be accomplished by using a layer mask, which is linked to a pixel layer or an adjustment layer. The layer mask hides parts of the layer to which it is linked, so those parts won't appear in a final version of the edited picture. A layer mask may be black and white or contain shades of grey. What is black on a mask will not be visible in the final picture. What is grey will be more or less transparent, depending on the shade of grey. As the mask layer can be both edited and moved around independently of both the background layer and the layer it applies to; mask layers give the user the ability to test different combinations of overlay. A working layer may refer to any type of layer, but specifically refers to the active layer on which the user is currently working (that is, currently editing).
A list of the layers is typically displayed in a panel in a sidebar of a graphical user interface.
It is known in image editing software to create a file that performs a series of editing steps on an image. The steps are recorded as a script and saved as a file. Thereafter, with a single click within the image editing software, the script is performed on the current image. With current image editing software, editing effects may only be applied to selected areas of the adjustment layers, but may not be applied to the pixel layers.
In order to apply a plurality of effects to pixel layers, a user must manually perform the steps of selecting an effect, creating a new layer (adjustment layer), making a selection of the area to which the effect is to be applied, then double clicking to apply the effect to the selected areas. To apply another effect, these steps must be performed again. In order to change an effect that was just applied, the layer on which the effect was applied must be deleted and the steps noted above repeated once again. In order to change the effect later in the editing process, a user must “undo” each completed step or restart the entire editing process with the original pixel layer.
Further, current image editing software only allows switching effects between adjustment layers. There is no means for switching between a pixel layer linked to a mask and an adjustment layer linked to a mask.
Therefore, there is a need for a method and apparatus for an improved workflow for digital image editing.
SUMMARY OF THE INVENTION
The present invention provides a method and apparatus for an improved workflow for digital image editing. In one embodiment, the method comprises accessing a file containing a plurality of effects to apply to an image. A plurality of visible layers of the image are merged, creating a merged layer. The plurality of effects are applied to the merged layer and a layer mask is installed on the merged layer. Finally, the method applies a plurality of user strokes made during the editing process to the installed layer mask.

DETAILED DESCRIPTION OF EMBODIMENTS
Embodiments of the present invention comprise a method and apparatus for applying a plurality of effects to an image. The embodiments utilize an image editing software which uses an effects module to apply a plurality of effects to the image. The method merges the visible layers of the image in the display. A layer mask is created and installed on the merged layer and all user strokes made during the editing process are then applied to the layer mask. Hence, as a user selects areas on an image, the effects are simultaneously applied using the layer mask. A marker may be linked to the layer for easy access later in the editing process. When the marker is selected by a user, the marked layer is made the layer displayed for editing by the user. Further, the present invention comprises a method for seamlessly switching from one effect to another when editing an image. The method stores a user selection in a temporary file. The user selection is made by the user on the working layer. The visible layers are merged and the effects are applied to the merged layer. The method then creates and applies a layer mask based on the user selection store previously. All user strokes made during the editing process are then applied to the layer mask. Hence, the method has enabled switching between a pixel layer with a mask to an adjustment layer with the same mask, keeping the masked and unmasked areas protected.
Various embodiments of an apparatus and method for an improved workflow for digital image editing are described. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the claimed subject matter. However, it will be understood by those skilled in the art that claimed subject matter may be practiced without these specific details. In other instances, methods, apparatuses or systems that would be known by one of ordinary skill have not been described in detail so as not to obscure claimed subject matter.
Some portions of the detailed description which follow are presented in terms of algorithms or symbolic representations of operations on binary digital signals stored within a memory of a specific apparatus or special purpose computing device or platform. In the context of this particular specification, the term specific apparatus or the like includes a general purpose computer once it is programmed to perform particular functions pursuant to instructions from program software. Algorithmic descriptions or symbolic representations are examples of techniques used by those of ordinary skill in the signal processing or related arts to convey the substance of their work to others skilled in the art. An algorithm is here, and is generally, considered to be a self-consistent sequence of operations or similar signal processing leading to a desired result. In this context, operations or processing involve physical manipulation of physical quantities. Typically, although not necessarily, such quantities may take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared or otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to such signals as bits, data, values, elements, symbols, characters, terms, numbers, numerals or the like. It should be understood, however, that all of these or similar terms are to be associated with appropriate physical quantities and are merely convenient labels. Unless specifically stated otherwise, as apparent from the following discussion, it is appreciated that throughout this specification discussions utilizing terms such as “processing,” “computing,” “calculating,” “determining” or the like refer to actions or processes of a specific apparatus, such as a special purpose computer or a similar special purpose electronic computing device. In the context of this specification, therefore, a special purpose computer or a similar special purpose electronic computing device is capable of manipulating or transforming signals, typically represented as physical electronic or magnetic quantities within memories, registers, or other information storage devices, transmission devices, or display devices of the special purpose computer or similar special purpose electronic computing device.
FIG. 1 depicts a block diagram of a system for providing an improved workflow for digital image editing, according to one or more embodiments of the invention. The system 100 simplifies the workflow for applying a series of effects to an image 116. The system 100 comprises a computer 102 and a display 128.
The computer 102 comprises a CPU 106, support circuits 108, and a memory 110. The computer 102 is a type of computing device (e.g., a laptop, a desktop, a Personal Digital Assistant (PDA) and/or the like) known to one of ordinary skill in the art. The CPU 106 may comprise one or more commercially available microprocessors or microcontrollers that facilitate data processing and storage. The various support circuits 108 facilitate the operation of the CPU 106 and include one or more clock circuits, power supplies, cache, input/output circuits, displays, and the like. The memory 110 comprises at least one of Read Only Memory (ROM), Random Access Memory (RAM), disk drive storage, optical storage, removable storage and/or the like. The memory 110 comprises an operating system 112, image editing software 114, an effects module 118, a layer switching module 120, and an image 116. The image 116 comprises a plurality of layers 122.
According to some embodiments of the invention, the operating system (OS) 112 generally manages various computer resources (e.g., network resources, file processors, and/or the like). The operating system 112 is configured to execute operations on one or more hardware and/or software modules, such as Network Interface Cards (NICs), hard disks, virtualization layers, firewalls and/or the like. Examples of the operating system 112 may include, but are not limited to, Linux, Mac OSX, BSD, UNIX, Microsoft Windows, and the like. The image editing software 114 calls upon commands associated with the operating system 112 (i.e., native operating system commands) to perform various operations, such as editing, applying effects and/or the like, as generally performed by known image editing software applications, such as ADOBE® PHOTOSHOP®, available from ADOBE Systems Incorporated, San Jose, Calif.
According to some embodiments, the effects module 118 applies a plurality of effects to the image 116 on the display 128. The layer switching module 120 allows for seamlessly switching from one effect to another when editing the image 116. The image editing software 114 may include, ADOBE® PHOTOSHOP® Elements, available from ADOBE Systems Incorporated, San Jose, Calif. or any image editing software which uses layers and masks for image editing.
According to some embodiments, the effects module 118 receives an effect or a file containing a series of effects to be applied to the image 116. The effects module 118 applies the effects on the image 116 in real time as the selection for where the effect is to be applied is made. The effects module 118 merges all visible layers 122 of the image 116 and applies the effects to the merged layer. The effects module 118 then creates a layer mask and links it to the merged layer. All user strokes input for image editing are now applied to the merged layer+layer mask by making these linked layers the working layer.
According to some embodiments, the layer switching module 120 advantageously enables easy switching from a first effect to a second effect. A user selects a first effect to apply to an image 116, for example, the image 116 contained on the background layer. As the user makes a selection, the first effect is applied to the image 116. The layer switching module 120 creates a layer with a mask in the layers panel above the background layer. When the user then selects a second effect, the second effect is applied to the image. The layer switching module 120 saves the mask in a temporary channel. A channel is similar to a layer. A channel stores a selection as an editable mask in a Channels panel (similar to the Layers panel). The channel, which contains the selection, may be used to reload a selection at any time, or as in the present case, to load it into another image, i.e. to apply the selection to another layer. The layer switching module 120 deletes the layer that was previously created in the layer panel above the background layer and creates a merged layer in the layer panel on top of the layers below, in this example, the background layer. The second effect is applied and the layer mask which was stored in the temporary channel is saved to this merged layer.
FIGS. 2A-2C collectively illustrate the use of layers and layer masks as performed by the system 100 of FIG. 1. FIG. 2A depicts an image 202 displayed for editing. The image 202 is a pair of pink roses with green leaves. The first time the image 202 is opened with the image editing application, a background layer 204 is created as shown in the layer panel 210. A lock icon 206 denotes that this background layer 204 cannot be altered. The eye symbol 208 denotes that this layer is currently visible
FIG. 2B shows the application of an effect to the image 202. The background layer 204 is copied to create layer 212. Now two layers are shown in the layers panel 210. The Sketch effect 214 is then applied to the layer 212. Note that although the display shows an edited image 202, the original image in the background layer 204 is not altered.
FIG. 2C shows a layer 216 with a mask 218. The layer 216 creates a black and white effect on the image 202. If the layer 216 did not have a mask 218, the image 202 would appear to be a black and white version of the original image of the background layer 204. However, the mask 218 has been created on this layer 216. The mask 218 is a white box with areas of black. Where the mask 218 is black, the black and white effect is concealed. Where the mask 218 is white, the black and white effect is revealed. Hence, when this layer is selected to be a visible layer (by selecting the eye icon), the flowers appear pink because the black area of the mask conceals the black and white effect and the rest of the image 202 appears in black and white, because the white area of the mask reveals the black and white effect.
FIG. 3 depicts a flow diagram of a method 300 for applying effects as performed by the effects module 118 of FIG. 1, according to one or more embodiments of the invention. The method 300 starts at step 302, and proceeds to step 304. At step 304, the method 300 accesses an original image. Every image has at least one layer, such as an image (pixel) layer. When a user first opens an image, a background layer is created for the original image. This background layer is an unalterable image layer that forms the basic layer upon which any and all subsequent editing is performed. A layer separate from the background layer is created each time text or any other modification (adjustment) is made to the original image. All edits are performed on adjustment layers, thereby allowing for editing without altering the original image. The method 300 proceeds to step 306.
At step 306, the method 300 displays to a user using a graphical user interface, the original image as an unalterable background layer along with a plurality of pixel layers, adjustment layers, and any other type of layer created when editing the original image. The layers are stacked one on top of the other to give the appearance of a single image upon display or printing. An effect applied to one area of the original image may be saved in one adjustment layer, while a change in color to another area of the original image may be saved in another adjustment layer. The image displayed on the graphical user interface is the cumulative effect of all of the layers applied to the background layer, in their current order. A reordering of layers may result in a different resulting appearance of the displayed image. A list of the layers in their current order is displayed on a sidebar of the display. The layers may contain markers. A marker is a quick way for a user to find a layer of interest. When a user performs a mouse click on a marker in the sidebar, the associated layer is revealed to the user and becomes the new working layer (i.e., the active layer for editing). The method 300 proceeds to step 308.
At step 308, the method 300 receives an effect that the user has selected to apply to an area of the image. This may be a single effect or it may be a file containing a series of steps, each step representing the application of a single effect. The method 300 proceeds to step 310. At step 310, the method 300 receives a selection location. This selection location is a point in the image where a user has placed a mouse pointer. The user will drag the mouse pointer around the image. Where the user drags the mouse will define an area of the image where the user would like to see the effect applied. The method 300 proceeds to step 312.
At step 312, the effect, or series of effects is applied to the image in the selected location as further disclosed in FIG. 4 below. The method 300 proceeds to step 314 and ends.
FIG. 4 depicts a flow diagram of additional details of a method 400 for applying the effect(s) to a selection location as depicted from FIG. 3, according to one or more embodiments of the invention.
The method 400 starts at step 402, and proceeds to step 404. At step 404, the method 400 merges the existing visible layers (adjustment and pixel layers) and copies (duplicates) them to a new layer comprising a combination of the images and effects from the visible layers. During the image editing process, any number of layers representing edits to the original image may be created. This allows the user to experiment with different effects alone and in combination on the original image. For example, if the image were a flower, one layer may change the color of the flower to yellow. Another layer may change the color to red. One layer may make the background color blue, while another layer may make the background color green. However, only a few of the layers are currently selected by the user to be visible in the display, for example, the yellow flower with the green background. Only the layers that are currently visible are merged so their effects can be judged by the user. Accordingly, these may be both pixel layers as well as adjustment layers. These visible individual pixel and adjustment layers, however, are untouched. The merged layer comprising the combined effects of the visible layers is, as noted above, what is copied, to a new layer. The merged layer is set as the current working layer. This is the active layer to which the effect(s) is/are being applied. The method 400 proceeds to step 406. At step 406, the method 400 applies the effects on the merged layer. The method 400 proceeds to step 408.
At step 408, the method 400 creates a layer mask and installs it on the working layer. This layer mask and the working layer are now linked. The method proceeds to step 410. At step 410, the method 400 applies user strokes input for image editing onto the layer mask. As the user drags the mouse pointer so as to select various regions on the image, the selected regions get unmasked (that is, visible), while the rest of the effect-applied regions are hidden. Optionally, after the effect is applied, a marker may be linked to the working layer+mask layer. The marker may be used to automatically return to this layer later in the editing process. The method 400 proceeds to step 412 and ends.
FIG. 5 depicts a method 500 for switching from one effect to another as performed by the layer switching module 120 of FIG. 1, according to one or more embodiments of the invention. Prior to initiating method 500 a user applies a first effect to a selection of an image. A layer with a mask is created in the layers panel above the other layers in the panel. This is the current working layer. The method 500 is initiated when the user selects a second effect to apply to the image.
The method 500 starts at step 502, and proceeds to step 504. At step 504, the method 500 copies the user selection of the current working layer and stores it in a temporary channel. A channel is similar to a layer. A channel stores a selection as an editable mask in a Channels panel (similar to the Layers panel). The channel, which contains the selection, may be used to reload a selection at any time, or as in the present case, to load it into another image, i.e. to apply the selection to another layer. The method 500 proceeds to step 506. At step 506, the method 500 merges the visible layers as described above in step 404 of method 400 above. The method 500 proceeds to step 508. At step 508, the method 500 applies the effect to the merged layers as described in step 406 of method 400 above. The current working layer is the merged layer. The method 500 proceeds to step 510.
At step 510, the method 500 creates a layer mask based on the user selection copied above in step 504 (which was stored in the temporary channel) and installs the layer mask on the current working layer. The method 500 proceeds to step 512. At step 512, the method 500 applies the user strokes input for image editing to the layer mask by making the linked merged layer+layer mask the working layer. The method 500 proceeds to step 514 and ends.
